Multi-station downflow centrifugal separation method and apparatus for separating particulate matter from gases

Patent ·
OSTI ID:5610206
The method involves conducting the gas through a plurality of particulate matter separating stations, serially. In each station the gas is centrifuged in an annular channel and then turned inwardly, to leave particles behind and conduct the particle-removed gas away therefrom. In the successive stations, the gas is centrifuged or swirled with differing force levels, and particles of differing sizes are separated out. The apparatus comprises a vessel in which are positioned a plurality of serially arranged separating stations. Each station has vanes for imparting a swirling, centrifugal motion to gas introduced into the vessel, and annular channels along which to conduct the swirling gas. Each station has a central, slotted tube, concentric with the channel, through which to vent the particle-separated gas, and the annular channels have terminations which define repositories for separated particles.
